Silver Deposition on Chemically Treated Carbon Monolith
Апстракт
Carbon monolith was treated with HNO(3), KOH and H(2)O(2). Effects of these treatments on the surface functional groups and on the amount of silver deposited on the CM surface were studied by temperature programmed desorption (TPD) and atomic absorption spectrometry (AAS). As a result of chemical treatment there was an increase in the amount of surface oxygen complexes. The increase in the amount of silver deposit is proportional to the amount of surface groups that produce CO under decomposition. However, the high amount of CO groups, decomposing above 600 degrees C, induces the smaller Ag crystallite size. Therefore, the high temperature CO evolving oxides are, most likely, the initial centers for Ag deposition.
